If you have ever had to adjust to a new time zone, you have noticed that it takes a while before you start to feel normal again. By shifting your sleep and activity schedule, you have altered the pattern of your body's circadian rhythms....

Students practice the engineering design process as they explore devices used to measure changes in temperature. They work in teams to design, build, test, and evaluate their own temperature gauge made from everyday materials.

Use this online activity to explore how various substances respond to changes in temperature. Learn how to calibrate a thermometer.

This site from the U.S. Geological Survey provides great definitions of seven measurements that can be taken on water. Includes pH, dissolved oxygen, and turbidity. Click Home to access the site in Spanish.

Instructions for how to make an electrical thermometer. The electrical thermometer works like this - the design consists of four resistors each made from about 40 meters of very thin copper wire. The electrical resistance of wire changes...

This resource explains the structure of the metric system of measurement; the basic units of measurement for length, volume, and mass; and provides charts for each type of measurement. A chart of customary US units is also given.

This micro-field guide was created by 5th and 6th graders in Marlboro, Vermont. Groups of 3 or 4 students worked together to investigate their own 3 by 3 foot research plot, over multiple visits, and then created a field guide to their...

This lesson plan familiarizes students in grades 4-6 with using the metric system and performing conversions.

Look to this site for many important numbers and conversion factors used between the metric system and the customary system, such as speed of light, body temperature, distance from sun to earth, plus more.

Harmful algal blooms occur when algae, which form the base of the ocean food web, grow in massive numbers and produce toxic or harmful effects on people, fish, shellfish, marine mammals, and birds. In this project you will learn how to...

This activity introduces students to the complex chemistry of estuarine water. Students investigate how chemical and physical water quality factors-pH, temperature, dissolved oxygen, and salinity-change and interact over varying time...
